Storm sash and screen fastener



STORM SASI-I AND SCREEN FASTENER.

the screen or the storm sash.

Another object is to provide such a fastening device which is adapted to remain permanently upon the outside wall of the window frame, and in readiness at all times to receive the stormjsash or the screen frame 1 as the case may be, and to clamp the same against the said window "frame, by a simple cam action, to exclude flies or other insects in summer time when the screen frames are in position, or to exclude the cold of winter when the storm sash is being used.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawing forming a part of this specifica tion; it being understood however, that while the drawing shows a practical form of the invention, the'latter is not to be confined to strict conformity therewith, but may be changed or modified, so long as such changes mark no material departure from the salient features of the invention, as

specifically pointed out in the appended claims. I

I In the drawing, in which similar reference characters designate corresponding parts through the. several figures Fig. 1 is a horizontal sectional view through one sideof a window frame with a storm, sash in position and showing the improved fastener holding the latter against the former.

Fig. 2 is a front elevation of the same.

Fig. 3 is a side elevation thereof and showing a portion of the window frame in verti cal section.

Referring to the drawing, there is illustrated a portion of an ordinary window frame 1, as commonly constructed, and pro vided with the usual vertical grooves or channels 2 for the window sashes (not Specification of Letters Patent. Patented May 2, 1922.

shown). The outside plate 3 of the window frame, which is adapted to lie flat against the outside of the house or building, is generally set back somewhat from the inner edge of the outer bead 4, thus providing a seat 5 into which the storm sash 6 may be fitted to rest upon the window sill 7 below. as clearly shown in Fig. 1 of the drawing. The seat 5 extends across the top of the frame and along the sides thereof, and it will be seen that, while a storm sash6 having a pane of glass 6 included therewith to exclude the cold is shown in the draw ing, a similar frame 6 provided'with a fly screen in place of the glass ,may be readily inserted into said seat to rest upon the window sill 7, in the same manner for the purpose of excluding insects, etc.

The storm sash or'screen is adapted to be held in such position in the seatrprovided in the window frame by a plurality of fasteners located at the sides thereof and on the outside of the building, such fas teners being secured to the outer face of the side plates 3, experience having shown that four of such devices are sufficient to hold the said frame securely in place, two being near the top of the frame and two at the lower portion thereof. The number'of fasteners to be used, however, is optional, as will be understood, and it has been deemed suflicient, in the drawing, to illustrate only one of such devices.

The fastener comprises a'bracket B so formed as to be readily stamped from suitable sheet metal, and bent to provide an elongated base plate 9 having, along its long sides, perpendicularly disposed side walls 10,-parallel to each other and arranged in a vertical. plane when the base plate 9 is properly secured to the outer face of the side plate 3 of the window frame, as by screws '11or other suitable fasteners.

formed of some suitably sized rod iron which traverses suitable apertures provided ill the extended portion of the side walls.

At its inner end, or that end adjacent to the frame 6, the cam shaft is provided with an eccentrically disposed cam 13 preferably formed by a looped continuation of the rod forming the shaft 12, and at the opposite end the said shaft, at the outside of that wall 10 of the bracket farthest removed from the frame 6, is provided with a crank-arm 14 which may be secured thereto or formed integrally at the end of the shaft, and which prevents the removal of said shaft fromits journals in the side walls 10 in a direction toward the said frame, the cam loop 13 acting in a like manner to prevent the removal of the shaft in the opposite direction.

The bracket with the cam and cam shaft mounted therein, is secured to the plate 3 in a certain spaced relation to the edge of the frame 6 which in some cases, as illustrated in the drawing, may project somewhat outwardly beyond the face of the plate 3, depending upon the thickness of the material from which the frame is made while, as will be understood, in other cases the face of the frame may not come out as far as the face of the side plate, but in either event the device is capable of clamping and holding the frame in position within its seat 5.

The length of the shaft 12 is such, that when the same is shifted to the left (as viewed in Fig. 2 of the drawing), or in a direction towards the frame 6 and the crank arm 14: abuts against the outer face of the adjacent side wall 10, the eccentric cam 13 is in overriding relation to said frame as shown in said figure, and it is only necessary to turn the shaft 12 over and inwardly, towards the face of the frame by means of the crank arm 14 in order to bring the everwidening radius of the eccentric loop into playagainst said frame to be frictionally engaged therewith, and to rigidly clamp the same in its seat at the outside of the window frame, such frictional engagement being facilitated by milling the periphery of the cam, as at 13 or otherwise roughening the same.

IVhen it is desired to release the frame 6 for the purpose of cleaning the same or for washing the windows, or for changing the storm sash for the screen or vice versa, it is only necessary to turn the shaft and the cam in a direction to release the frictional engagement of the latter with the face of the frame, and then move the shaft in a direction to cause the cam to approach the adjacent wall 10 of the bracket, when the same will clear the edge of the frame, as indicated in dotted lines in Fig. 1 of the draw'ingand the said frame may be freely withdrawn from its seat.

From the foregoing, it will be seen that an extremely simple and cheaply manufactured sash fastening device has been pro vided, comprising a minimum number of parts which are of light construction, and that the device may be easily and quickly secured to the outside of the window frame in proper position to engage the storm sash or screen, by any unskilled person, to remain in such position and to be easily operated to secure the frame in position without dama ing or marring the same.

IVhat isclaimed is I 1. In combination with a bracket provided. with journals, a shaft rotatably and slidably mounted in said journals, said shaft being bent at one end in the shape of a spiral and in a plane at right angles to the shaft to form a cam.

2. In combination with a storm sash or screen frame, a bracket mounted on the window frame and provided with journals, a transversely-disposed shaft mounted for rotative and slidable movement in said journals, means on the shaft to provide for retation thereof, and a cam at one end of the shaft, adapted to be rotated by the shaft and cause the cam to grip the window sash and hold the same in position.

3. In combination with a bracket havin alined journals, a transversely-disposed shat mounted for rotative and slidable movement in said journals, said shaft having a crank arm at one end and an eccentrically mounted loop at the other, said shaft, loop and crank arm being formed in one piece. 1

1. A storm sash and screen frame fastener comprising a bracket adapted to be secured to the outside of a window frame in spaced relation to the edge of the storm sash or screen frame, said bracket having outstanding substantially parallel side walls provided with alined perforations constituting journals, a transverselydisposed shaft mounted for rotative and slidable movement in the journals, said shaft having a crank arm at the end farthest removed from the storm sash or screen frame. said shaft extending inwardly beyond the other side wall in Own riding relation to said sash or frame, and

there formed into an eccentricallymounted loop having a roughened periphery to be brought into frictional engagementwith the sash or frame when the shaft is 1ongitudinally shifted in its journals in one direction and to be removed from such overriding relation when the shaft is shifted in an opposite direction.

In testimony, that I claim the foregoing as my own, I have hereto afiined my signature.
